Abstract
The utility model relates to a bracket specially used for a high anti-interference infrared receiver head, comprising a base plate and a shielding cover, wherein the shielding cover is provided with an infrared receiving window provided with a shielding mesh, and the shielding cover and the base plate are connected with each other to form an integral structure by a top shielding plate positioned between the shielding cover and the base plate. By adopting the integral structure, compared with the prior art, the bracket specially used for the high anti-interference infrared receiver head has simple manufacturing technique, reduces the working procedures of manpower assembly and saves the labor cost. In addition, shielding plates are arranged on the tops and at the two sides of containing spaces of a photosensitive component as well as of a circuit component; furthermore, the X-shaped shielding mesh is adopted, the installing and connecting position of the photosensitive component is separated from that of the circuit component, and the circuit component is shielded by the shielding cover so as not to be exposed by the infrared receiving window, so that the anti-interference performance is good, the disordered electromagnetic signals can be filtered and removed, and the reliability of reception can be enhanced.
Description
Technical field
The utility model relates to a kind of infrared remote control and receives a parts, is specifically related to a kind of high noise immunity infrared receiving terminal special stand.
Background technology
Along with household electrical appliance the sensitivity of remote control is required more and more higher, and progressively the increasing of household electrical appliance, electromagnetic interference (EMI) and various light disturb more and more stronger, need improve the anti-interference of infrared receiving terminal.
Anti-interference infrared receiving terminal special stand is in the market combined by modes such as buckles by substrate that is separated from each other and screening cover mostly, have the infrared receiving window of band gauze screen on the screening cover, have the photosensitive components attaching position and the circuit unit attaching position that are separated from each other on the substrate.The shortcoming of this infrared receiving terminal special stand is: because substrate and screening cover need be distinguished moulding, the manufacturing process complexity need manually be assembled, and has increased human cost.In addition, the gauze screen at above-mentioned infrared receiving window place generally adopts cross shape, and shield effectiveness is not ideal enough.
The utility model content
The purpose of this utility model is in order to overcome the defective that prior art exists, a kind of easy to process, the high noise immunity infrared receiving terminal special stand that shield effectiveness is good that provide.
For achieving the above object, the utility model has adopted following technical scheme: a kind of high noise immunity infrared receiving terminal special stand is provided, comprise substrate and screening cover, the infrared receiving window that has the band gauze screen on the described screening cover, described screening cover and substrate are by the structure that is connected as a single entity of the top barricade between them.
According to the utility model, described screening cover and substrate almost parallel, described top barricade is vertical substantially respectively with substrate with described screening cover.
According to the utility model, have the photosensitive components attaching position and the circuit unit attaching position that are separated from each other on the described substrate, the view field of described infrared receiving window on substrate covered described photosensitive components attaching position substantially, and described circuit unit attaching position then is positioned at outside this view field.
According to the utility model, the both sides of described screening cover have the side barricade respectively.
According to the utility model, described gauze screen be shaped as " * " shape.The results showed, adopt the gauze screen of this shape, can obtain more satisfactory shield effectiveness.
Compared with prior art, the operation that the utility model manufacturing process is simple, reduced artificial assembling has been saved human cost; In addition, because the top and the both sides of the spatial accommodation of photosensitive components and circuit unit all have barricade, and adopted the gauze screen that is " * " shape, photosensitive components attaching position on the substrate and circuit unit attaching position are separated from each other, circuit unit is shielded by screening cover and can not exposed by infrared receiving window, therefore anti-interference is good, but the mixed and disorderly electromagnetic signal of filtering has strengthened reception reliability.
